Definitions

  • the invention relates to a fastening element consisting of two axially collapsible half-shell-shaped anchoring elements which are tapered in parallel on their mutually facing sliding surfaces and which additionally overlap to form a circular cross section.
  • Fastening elements of the type mentioned above have a very high expansion capacity with a low notch effect in the borehole.
  • fasteners are particularly suitable for small installation depths, which are desirable for fastening in ceilings.
  • cracks have to be taken into account which lead to an expansion of the bore receiving the fastening element. If a fastening element for the ceiling lacks the possibility of expanding to compensate for the expansion of the borehole, this can lead to failure of the anchoring.
  • the invention is therefore based on the object of providing a fastening element which expands when a borehole widens as a result of cracking.
  • this is achieved in that on one anchoring element in extension of its smallest cross-section a tab with an opening for hanging wires, perforated bands or the like. Is arranged, which is wider than the diameter of the hole receiving the fastener.
  • the arrangement of the tab in the extension of the smallest cross section of the one anchoring element means that the load acts on the anchoring element, the largest cross section of which is located in the borehole depth.
  • the fastener is wedged in the borehole by driving in the other anchoring element, the bevel of which runs in the opposite direction.
  • an axial displacement of the anchoring element connected to the tab takes place due to the weight load on the tab due to the suspended object until a new wedging takes place in the borehole.
  • the spreading pressure With increasing tension on the tab, the spreading pressure also increases, so that high holding forces can be achieved by this spreading effect even when the borehole widens.
  • the anchoring element used for wedging is pushed back so far that the cross section of the two anchoring elements resulting from the overlap is smaller than the bore diameter.
  • the tab which is wider, serves as a limitation for the insertion depth. than the borehole diameter.
  • the anchoring elements can be provided with successively arranged cutouts in the longitudinal direction. This design reduces the rigidity of the half-shell-shaped anchoring elements, so that they can better adapt to the irregular shape of the borehole. This achieves a large-area contact with the borehole wall, which leads to anchoring that is gentle and at the same time enables higher holding values.
  • the two anchoring elements can be held together with shearable connecting means, such as beads, rings or the like, in a position in which the complementary cross section of the two anchoring elements is smaller than the bore diameter.
  • shearable connecting means such as beads, rings or the like.
  • the anchoring element to be driven can be provided with radially projecting flanges, which comprise the anchoring element provided with the fastening tab.
  • the fastening element can thus be inserted into the borehole until the fastening tab comes into contact with the outer surface of the masonry. Now the anchoring of the fastening element is brought about by striking the other anchoring element, which is guided both through the flanges and through the borehole.
  • the flanges of one anchoring element can be guided on the fastening lug of the other anchoring element and the fastening lug can have a widening on its free end face.
  • the other anchoring element is preferably encompassed in the region of the fastening lug, since this remains outside the bore and therefore no obstruction occurs during the anchoring process.
  • the widening of the fastening tab also creates a stop, so that even in a somewhat narrower borehole, the other anchoring element, which is supported on the widening by the flanges, is pushed into the borehole by hitting the fastening tab.
  • the length of the guide can correspond to the height of the flange plus the drive-in path of the anchoring element to be anchored. This measure results in a predeterminable minimum drive-in distance.
  • the breakthrough offset from the center of gravity can have a nose-shaped widening, through which a projection arranged on the bent end of the wire can be pushed through if the wire is in a corresponding position rotated from the perpendicular direction Wire can be reached in the opening of the tab.
  • the fastening tab can have longitudinal slots into which the flanges engage and encompass the web remaining between the slots.
  • the front end of the anchoring element to be driven can have an extension which is pushed into the half-shell-shaped cavity of the other anchoring element.
  • the profile of the bent extension can correspond to the profile of the cavity.
  • the other can Verank ceremoniessele- m ent with projecting into the cavity beads be provided, which support the extension of the collectible anchoring element against sliding back.
  • the two anchoring elements are displaced so far that the cross section of the overlapping anchoring elements is smaller than the borehole diameter. In this position, the one anchoring element is supported by the projection on the beads. This prevents the anchoring element to be driven from sliding back when the fastening element is inserted.
  • a tongue can be arranged in the region of the rear end of the anchoring element to be driven, which tongue clamps into an opening in the other anchoring element.
  • the fastening element 1 consists of the two anchoring elements 2 a, 2 b, which are bevelled parallel to one another on their mutually facing sliding surfaces 3.
  • the two anchoring elements 2 a, 2 b are held together via a bead connection 4 in a position in which the cross section of the overlapping anchoring elements is smaller than the diameter of the bore 5 in the masonry 6.
  • the fastening element 1 is thus far into the borehole 5 without difficulty to use until the on the anchoring element 2 a arranged tab 7 comes to rest on the masonry surface.
  • the tab 7 is arranged in an extension of the smallest cross section of the anchoring element 2 a, the largest cross section of which is in the depth of the borehole.
  • the anchoring element 2 b not provided with the tab 7 is driven into the borehole 5 with hammer blows, if necessary using an auxiliary tool.
  • the bead connection 4 is sheared off and the sliding movement is thus made possible.
  • the two anchoring elements 2 a, 2 b are radially outward pressed and anchored in borehole 5. If an object, for example a pipe, is suspended from the wire 9 drawn through the opening 8 of the tab 7, the tensile force on the anchoring element 2 a, which has a larger cross section in the depth of the borehole, results in a spreading effect, which enlarges the borehole 5. can compensate for example by crack formation.
  • the relatively stiff half-shell-shaped anchoring elements 2 a, 2 b have cutouts 10 arranged one after the other in the longitudinal direction, which reduce the rigidity of the anchoring elements.
  • the two anchoring elements 2 a, 2 b are connected with a ring .11, which is inserted in an embossed groove 12 of the two anchoring elements 2 a, 2 b and is sheared off when anchoring the fastening element.
  • the opening 8 designed as a hole in the tab 7 can also be designed as a rectangular opening for hanging tapes. The width of the tab 7 is chosen so that sufficient contact with the masonry surface is achieved.
  • the fastening element 1 also consists of the two anchoring elements 2a, 2b, which are bevelled parallel to one another on their mutually directed sliding surfaces 3.
  • the two anchoring elements 2a, 2b are held together via the two radially projecting flanges 20 and the fastening tab of the one anchoring element, in a position in which the cross section of the overlapping anchoring elements is smaller than the diameter of the bore 5 in the masonry 6.
  • the flanges 20 can be supported on the widening 21 of the fastening tab 7, so that the fastening element can be pushed into its anchoring position even in a very narrow borehole by light impacts on the fastening tab 7.
  • the latter has a projection 22 arranged at its bent end, which can be pushed through the opening 8 and the nose-like extension 23 arranged in the opening when the wire 9 is rotated from the perpendicular direction. After the wire has been turned again in the perpendicular direction, the projection 22 engages behind the rear side of the fastening tab 7, so that a securing against unhooking of the wire 9 is achieved.
  • the fastening tab 7 has two parallel slots 24, into which the flanges 20 ′ arranged on the one anchoring element 2b engage. These flanges 20 ′ encompass the web 25 remaining between the two slots 24.
  • the two anchoring elements 2a, 2b are held together in a position in which the cross section of the overlapping anchoring elements is smaller than the diameter via the tongue 31 of the other anchoring element 2b, which is pressed into the opening 30 of the one anchoring element 2a the bore 5 in the masonry 6.
  • the anchoring element 2b is supported by the tongue 31 on the one hand and by the beads 32 projecting into the cavity on the other hand, so that even in a very narrow borehole by light impacts on the fastening tab 7 Fastening element can be inserted in its anchoring position.
  • the extension 33 arranged on the anchoring element 2b and bent into the half-shell-shaped cavity of the other anchoring element 2a serves as a guide, so that the thin-walled sliding surfaces of the two anchoring elements slide on one another even if the borehole is drilled too large.
